METAL WHEEL.

SPECIFICATION forming part of `Letters Patent No. 609,258, dated August16, 1898. Application filed January 28,1898. Serial No. 668,294. (Nomodel.)

To @ZZ whom it may concern:

Be it known that I, DANIEL J.y C. ARNOLD, a citizen of the UnitedStates, and a resident of New London, county of Huron, State of Ohio,have invented certain new and useful Improvements in Metal'Wheels, ofwhich I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in metal wheels; and the object ofthe invention is to provide a durable wheel of'great strength adaptedfor use in all kinds of agricultural machinery or heavy trucks.

My invention consists in the sleeved hub portions and independentsheet-metal spokes, with the central sheet metal sleeve andclamping-plates, and in the means for attaching the spokes thereto andto the metal rim, as hereinafter described, shown in the accompanyingdrawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure lis a perspective view of theinvention. Fig. 2 is a central longitudinal section, and Fig. 3 isdetail of rim in section of a modified form.

In the figures, 1 is the larger hub-section, upon the screw-threadedextremity2 of which is secured the outer portion 3 in the manner of anut and which is tapered within and without. Each of these sectionsisprovided with an inwardly-turned iiange 4, between which are secured theinner and outer circular clamping-plates 5 and 6, arranged in pairs. Theouter plates 5 are loose and inwardly flanged at 10, bearing one uponthe tapered surface of the inner portion of the hub, the other upon thedoubly-tapered ring 7, which is sleeved upon the outer portion and abuisagainst the outer hub-flange 4.

The spokes 8 are formed of band metal doubled into a lJ-shaped section,as seen at 9, to increase their, strength and'abut against theinwardly-turned and tapered Iianges 10 of the outer clamping-plates 5.

6 are the inner clamping plates, between which andthe outer plates aresecured the spokes 8 by means of the elongated rivets or keys 11. One ofthese plates is formed in continuation of the sheetfanetal sleeve 12,which encircles the taper hub and protects it from dust, so `that themovements of the wedgeshaped` ring 7 thereon shall be unimpeded.Thesleeve also separates the pairs of clamping-plates, so as to producea staggered. construction of the spokes. The outer extremities of thespokes 13 retain their flattened shape and arelattached, by means ofrivets 14, either directly through the metal rim 15, as shown in Fig.2,0r through a flange thereon, as shown at 16, Fig. 3. The sleeve 12bears upon the inwardly turned and tapered extremities of the outerplates, which also pass under the extremities of the spokes and underthe outer plates, so that the action of the outer portion of thehub'against the wedge-ring and outer plate serves to tighten all theparts together and also makes all the partsinterchangeable.

An octagonal shape is given the outer hub at 17 for the use ofthe wrenchin screwing them together, and notches 18 are made in the flanges 4 forthe introduction of small bolts 19 to prevent the sheet-metal flangesfrom turning on the hub.

Having Vdescribed my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a metal wheel, the combination with a cylindrical hub, of circularpressed plates encircling 'the same in pairs and adapted to secure theinner ends of metal spokes between them, one plate in each pair beingIianged to obtain a bearing upon the hub, substantially 'as described.

2. In a metal wheel provided with a cylindrical hub, pressed steelplates in pairs encircling the hub and securing the spokes between eachpair, in combination with a sleeve separating each pair of plates,flanged and tapered inner extremities of the outer plates upon whichsaid sleeve bears, and means for clamping the plates against the sleeve,sub` stantially as described.

3. In a metal wheel, the combination with a taper hub, of metal platesencircling the same in pairs between which the inner extrem!- ities ofthe spokes are secured, a metal sleeve having its bearing upon flangedand tapered inner extremities of the plates, a taper split ring uponsaid hub underneath one of said iianges, and means for clamping theparts securely together, consisting of a flange upon the hub and athreaded and iianged sleeve IOO bearing upon said ring and outer pairofi` plates, substantially as described.'

4. In a metal Wheel, the combination with an inner hub portion, taperedWithin and Without, of an outer portion adapted to be screwed over thesame, outer and inner clamping-1anges arranged in pairs and adapted to`inclose the metal spokes, an extension of one of said inner ilangesadapted to encircle the tapered hub, and means for securing the flangesto the hub and for pressing the parts securely together, consisting ofinclined flanges upon the hub portions, and a Wedgering upon the taperhub abutting against the outer hub portion, substantially as described.Y

5. In ametal Wheel, hub portions provided with inwardly-inclinedflanges, sheet-metal Han ges secured between said hub-flan ges andDANIEL J. C. ARNOLD.
